近年来,中国西北部兰州-民和盆地的中铺地区河口群发现了一批恐龙骨骼化石和足迹化石。中铺地区的蜥脚类与兽脚类足迹组合相对丰富,但大多数标本保存较差。大夏足迹点发现了保存较好的类似亚洲足迹的跷脚龙类足迹(Asianopodus-like grallatorid tracks),足迹有着中趾弱前凸(weak mesaxony)。李家沟一号点的足迹组合包括了较大的兽脚类足迹和大型的、非三趾型四足类足迹,后者可能是蜥脚类足迹。李家沟二号点的足迹为多层的蜥脚类足迹,这表明了这类恐龙的活跃性,巨龙类的骨骸也可能来自同一层位。虽然中铺足迹组合不如同属河口群的盐锅峡足迹组合那么具有多样化与得以充分暴露,但依然体现了该地区以及中国早白垩世地层的典型足迹组合。
In recent years, a group of dinosaur bone fossils and footprints have been found in the mouth group of Zhongpu District, Lanzhou-Minhe Basin, northwestern China. In the shop area, the sauropods and theropods are relatively abundant, but most specimens are poorly preserved. The Great Summer Footprint spotted well-preserved Asianopodus-like grallatorid tracks with weak mesaxony. The footprint combination at Point Lijiagou includes a larger footprinting footprint and a large, non-three-toe type footprints footprint, which may be sauropod footprints. The footprint of Lijiagou Point 2 is a multi-layered sauropod footprints, indicating the activity of these dinosaurs. The dragon’s skeleton may also come from the same layer. Although the combination of the Zhongpu Footprint is not as diversified and fully exposed as the Yanghuoxia Footprint combination belonging to the Hekou Group, the typical footprints of the region and the Early Cretaceous strata in China are still reflected.
